Abstract: A method for a color coded filing system uses color codes for the sequencing elements of a sequencing scheme to provide unique color codes for the file designations of individual files. The method omits the color code for the last sequencing element of the file designation such that, when multiple files are arranged in order, the color codes form horizontal rows of easily discernible color blocks where the color blocks span multiple files. The file folder used in conjunction with the method has a pocket for a removable color code carrying medium. The pocket includes a window on the outside edge of the file folder. The window is aligned with the color codes on the carrying medium to permit direct viewing of the color codes. A graspable portion of the carrying medium extends through the window to aid in insertion and removal of the carrying medium.
